Weapons

Six phaser banks -- three each on the dorsal and ventral surfaces of the saucer section[2]; the forward ventral phaser bank was used most frequently.

Photon torpedoes fired from forward tubes -- originally built into the saucer, the tubes were moved to the "neck" of refitted Constitution-class starships[3]. There is also at least one aft facing photon tube[4].

A number of Class-Fshuttlecraft in an launch bay located in the aft section of the stardrive hull. The Enterprise is known to have carried at least two such shuttles, named Galileo and Columbus.[5] The USS Exeter carried four shuttlecraft. [6]
